UNLOADING CONVEYER.

Application filed October 26, 1922. Serial No. 596,972.

To all whom it may concern:

Be it known that 1 WILLIAM W. VVAL- LACE, a citizen of the United States, and a resident of Chicago, in the county of Cook 5 and State of Illinois, have invented an Improvement in Unloading Conveyers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention relates to unloading apparatus, and more particularly to a portable brick unloading apparatus adapted to quickly and economically unload bricks from a barge, car, wharf, or other storage place and transfer the same to a point relatively higher than such storage place.

My invention is particularly adapted for unloading brick from barges, such as a canal or river barge, into a truck or other Vehicle located on a wharf or any convenient point along the shore of a canal or river. The growth of the so-called Hudson River brick yards has been greatly retarded because of the fact that the bulk of their product has been loaded onto barges which are then sent through canals or along rivers to a discharging point where it has been necessary to unload the bricks from such barge onto a wharf or into a vehicle located on the wharf or shore and always the vehicle, such as a truck, is situated at a higher point than the deck of the barge on which the bricks are located. Various improvements have been made in the process of manufacturing bricks in the so-called Hudson River plants and one of the improvements consists in the use of mechanically operated loading devices which take brick from the kiln and load the same into, or onto, barges, the brick being picked up from the kiln in units of from two to four thousand bri'ck each and deposited bodily onto the barge in an economical manner thereby displacing the older method which consisted entirely of what was called the wheel barrow loading, workmen wheeling barrow loads of brick from the kiln onto the barge where they were stacked manually at either end of the barge, leaving on such barge a narrow transverse passage. In spite of the change "'"from manual to mechanical loading of the barges it has heretofore been necessary to unload such barge manually, the central transverse passage, of course, being utilized to assist in the unloading operation.

My present invention 'is designed to expedite the unloading'of brick from a barge onto a wharf or into a vehicle located on a wharf and to this end I have devised a portable unloading apparatus consisting essentially of a horizontal oonveyer, or a plurality of horizontal conveyers, cooperating with an inclined conveyer and which elevates and automatically dumps the brick onto a wharf or into a vehicle located on such wharf. The combination of a horizontal conveyer and an inclined conveyor is not new, but invariably material transported by the level conveyer is deposited at the receiving end of the inclined conveyer and the course of the material from the placing of the same onto the level conveyer until discharged by the inclined conveyer is in the same general direction and such combination cannot be made to work in the present situation due to the fact that the barge must lie closely adjacent to the wharf and the angle of the inclined conveyer would be necessarily so steep as to preclude the possiblity of the bricks moving upwardly with the conveyer. I have, therefore, in my present invention, arranged the level conveyer, or plurality of level conveyers, transversely of the barge with the receiving end of the inclined conveyer adj acent'the side of the barge remote from the wharf thus making it possible to have a comparatively gentle rise of the inclined conveyer and insuring a positive feeding of the bricks upwardly from the barge onto the wharf. To facilitate the transfer of bricks from the level conveyers onto the inclined conveyer I arrange deflecting devices at the discharge end of the level conveyers which cooperate with the booster belt, or conveyer, and whereby the bricks are shunted onto the inclined conveyer at the receiving end thereof.

As the barges carrying thelbrick are to be discharged at tide water points and as the height of the level of the water with respect to the wharf varies with the rise and fall of the tide, and as the inclined conveyer arranged in the rigid frame would at, for example, low tide bring the discharge end of such inclined conveyer at the proper ill) height over the wharf or over the truck to receive the brick on such wharf, while at high tide such discharging point would be at such height above the wharf as to cause injury or excessive breakage of the brick when discharged, I arrange the frame of the inclined conveyer in such a manner as to beable to lower the discharge end thereof relati 'ely to the receiving end, the discharge end being adjustable to any position within reasonable limits.

Associated with the frame carrying the entire unloading apparatus I arrange movable or slidable platforms on either side thereof and extending transversely of the barge and which are adapted for use by the workmen in loading thetopmost layers of bricks, or pile of bricks, on the barge onto the level conveyors, these movable or slidableplatforms being arranged to be moved within the frame or on either side thereof, at will, and when these frames are completely housed therein.

As the barge is gradually unloaded and bricks are taken from one end or the other of such barge and on either side of the central passageway, I arrange the unloading apparatus on caster wheels which are arranged on vertical axles to allow the entire framework to be moved laterally; that is, longitudinally of the barge in either direction, and which caster wheels may be turned through an angle of 90 for the purpose of locking the apparatus against lateral movement. Further, I also arrange the vertical axles of the caster wheels in the frame as to be vertically movable with respect to such frame, thereby making it possible to level the apparatus on the deck of the barge regardless of the inclination of such'deck.

Further features of the construction and arrangement of parts comprising my invention will be apparent as the description of the invention progresses.

Referring to the drawings, 10 designates an elongated rectangular frame work comprised of structural metal of desired size and shape. On each side of, and at each end of, this framework 10 is rotatably mounted a caster wheel 11, the bearing member 12 for each caster wheel being provided with a vertical shaft 13 threaded at its top end l-t and provided near its lower end with a squared or non-circular portion 15. On the threaded end 1 1 is an adjusting hand wheel 16 which bears against'the framework 10 and is utilized to raise or lower the frame 10 with respect to the caster wheel 11 for the purpose to be hereinafter described. livotally mounted to the f 'ame work 10 is a plate 17 which is provided with a squared or non-circular opening 18 therein that cooperates with the squared or non-circular portion 15 on the shaft 13 to prevent rotation of said shaft 13 and, therefore, relative movement of the caster wheel 11 with respect to the frame 10. By this means I am enabled to level up the frame 10 on an uneven support and may also move one or more of the caster wheels 11 relatively to the frame 10 to prevent lateral movement of said frame l0 on the support.

Mounted on the frame work 10 near one end thereof is a prime mover 9, such as an internal combustion engine, the main shaft 20 of this prime mover 19 being connected by chain 21 with a sprocket 22 fast to a shaft 23 that is rotatably mounted in suit able bearings on the frame work 10. Secured to the shaft 23 is a gear 24 that meshes with a gear secured to a shaft 26 that is rotatably mounted in suitable bearings on the frame work 10. Rotatably mounted in suitable bearings in-the frame work 10 is a shaft 27, it being understood that the shafts 2T, 26, and 23 are parallel to each other and also parallel to the main drive shaft 20 of the prime mover 19, and secured to the shaft- 27 near each side of the frame work 10 is a pulley 28.. fotatably mounted in each end, and at each side of the frame work 10 near the. top thereof are shafts 2!) to which are secured idler rollers 30, the shafts 29 being adjustable in their bearings by means of the adjusting screws 31. .\lso rotatably mounted at each side, and below the top sun face, of the frame work it) are shafts 3'3 and 33 respectively. the'shafts 3') having secured thercto idler rolls Ill and the shafts 9.3 liaving secured thereto idler rolls 35. The shaft 33 is made adjustable in its bearings by the adj nsting screw 36. Over the pulleys 28 and idler rolls 3t), 34, and 35 on each side of the frame work 10 passes an endless conveyer belt 37 the tension of which may be adjusted by the adjusting screws 31 and 36, as above described, and the upper reach of this belt lies substantially in the same horizontal plane as the top of the frame work 10. Secured to the shaft 27 is a sprocket Wheel 48 that is in alinement with the sprocket wheel 49 secured to the shaft 26 and over the sprocket wheels 48 and 49 runs a chain 50 which, as the main drive shaft 20 of the prime mover 19 rotates in the direction of the arrow shown on such prime mover, moves the upper reach of the conveyer belt 37 in the direction of the arrow, or to the left, as shown in Fig. 4. Secured to the frame work 10 adjacent the delivery end of the horizontal reach of the conveyer belts 37 are deflecting plates or chutes 51 Which defleet material carried by such belts onto the booster belt 43. Rotatably mounted in suitable bearings and lying parallel with the shafts 27, 26, and 23 is ashaft 38 to which is secured a roller 39, and rotatably mounted in adjustable bearings 40 on the frame work 10 is a shaft 41 on which is secured a roller 42, and over the rollers 39 and 42 runs an endless booster belt 43, the tension of this belt being adjusted by adjusting screws 44 associated with the bearings 40 and shaft 41. This booster belt 43 lies centrally, and extends longitudinally, of the frame work 10 and its top reach is practicallyhorizontal.

Built up on top of the frame work 10 and inclining upwardly at an angle from a point adjacent the mechanism above described to any convenient point and sup ported on the frame work 10 by members 45 is a frame work 46 which has rotatably mounted in its upper end rollers 47. Hingedly mounted on the shaft 52 to the lower roller 47 is a frame work which is provided on each side of the end adjacent the upper end of the frame work 46 with a forked plate 54, this forked end fittin over the shaft 55 of the upper roller 47. ivotally mounted on each of the forked plates 54 is a hook 56 which fits over the protruding end of the shaft 55 and locks the frame work 53 in alinement with the frame Work 46. The end of the frame work 53 remote from the frame work 46 is provided with a roller 57 and both the frame works 46 and 53 are provided with a plurality of idler rollers 58 on the lower surfaces thereof. The frame work 10 is provided with suitable adjustable bearings 59 in which is rotatably and adjustably mounted, by means of set screws 66, an idler roller 61, and on the shaft 27 is rotatably mounted a roller 62 to one end of which is secured a sprocket wheel 63 which is in alincn'icnt with a sprocket wheel 64 secured to the shaft 23, and over the sprocket wheels 63 and 64 runsa chain 6.3. Over the roller 6'3 and Idlers 61. 58. 47. and 57 runs endless elevating conveyer belt 66 and the diameter of the pulley 62 is so proportionedwvith relation to the inclination of the frame work 46 that the upper inclined reach of the belt 66 lies practically in a single inclined plane, it being assumed under these circumstances that the frame work 53 is in the position relative to the frame work 46 shown in Fig; 2. The shaft 20 of the prime mover l9 rotating in the direction of the arrow shown in Fig. 4 rotates the pulley 62 in such a direction as to give to the. upper inclined reach of the conveyer belt 66 a movement in the direction of the arrow shown in Fig. 4.

Secured to the end of the frame work 10 remote from the primemoverl!) are uprights 67, these uprights beingtied together at their upper ends and provided with an eye 68 adapted to receive the hook 69 secured to a block 70. Secured near the upper outer, or free, end of the frame work 53 is an eve 71. adapted toreceive the hook 72 se-urcd to a block 73, and a rope 74 reeves through the blocks and 73 to raise or lower the. outer, or free. end of the frame work 53. Normally the position of the frame work 53 relative to the frame work 46 is that shown in Fig. :2, but should it be desired to deposit material from the inclined conveyer belt 66 to a less height than that shown in Fig. 2, the hook 56 is removed from association with the protruding end of the shaft 55 and the rope 74 utilized to lower the outer, or free, end of the frame work 53 to any desired position relative to the frame work 46. the pulleys 47 under these conditions acting guide the endless conveyer belt 66 and thus provide means for articulating such endless conveyor belt.

The frame work 10 is provided with a plurality of uprights 75 which support a permanent canopy 76 which not only act; as a shelter for the workmen employed in operating the conveyor, but also acts as a protecting device for the conveyer belts which would otherwise be necessarily exposed to the weather. The frame work 10 is slotted at a plurality of points to receive slidable bars 77 which bars are arranged in pairs, as shown in Fig. 7, the bars '77 being each provided with a slot 78 in which slides a pin 79 secured to the opposite bar 77 of the pair. Also each bar is provided with a pin 80 which engages with the sides of the frame work 10 to prevent further inward movement of such bars. \Vhen one or the other of each of the pair of bars 77 are pulled outwardly, as shown in Fig. 7, a light runway or walk 81 may be placed thereon on which workmen may stand to lit) lit)

'essary.

operate the conveyers. Such walk 81 may be removed and the bars 77 of the pairs of bars that protrude laterally from the frame work 10 may be moved inwardly so that. all the bars on either side of the frame work 10 may be in their inward or closed position, as shown in Fig. 7 to the le ft, but with the construction shown, it is not possible for both of the bars of each pair of bars to be pulled outward at one and the same time.

My improved unloading conveyer is adapted particularly for use inunloading brick from canal or river barg'es onto a wharf or into a transporting apparatus placed on such wharf and I have, therefore, shown my improved device as being located in position on a barge 82 that is positioned adjacent a wharf or pier 83, a transporting apparatus such as a motor truck St being located on such wharf and in position relative to the upwardly inclined endless conveying belt 66 to receive the brick delivered therefrom. As the bricks are at present piled onto the barge by hand, being first brought onto such barge on wheel barrows, the building of the stack of brick on the barge takes place on either side of a substantially centrally located transverse 'passage and my present apparatus is designed narrow enough to be conveniently located in such central passageway. lVhen it is desired to unload the brick 86 from a barge 82, my apparatus is run onto such barge in the central transverse passageway 85 and onto caster wheels 11, and assuming that the wharf or pier 83 alongside of which the barge 82 is moored is on tide water and that such unloading process is to take place at low tide, the upwardly inclined frameworks 46 and '53 are left in the position shown in Fig. 2. the barge S2 is evenly loaded and therefore raises substantially on an even keelso that no adjustment of the frame work 10 is nec- IIaving decided on which side of the apparatus the brick are to be first unloaded, the workmen pull out from the sides of the frame work 10 the slidable bars 77, place their walk thereon, and the prime mover 19 being started in operation, the brick are removed from the pile of bricks and deposited on the substantially horizontal reach of the endless conveyer belt 37 located on the framework of the apparatus. These brick being carried in the direction of the arrow shown in Fig. 4, are deposited by such endless conveyer belt 37 onto the deflector or chute 51 which deposits them on the booster belt 43 which is designed to have a greater surface speed than the endless conveyer belt 37. Such booster belt 43 deposits the brick onto the upwardly inclined reach of the unloading conveyer belt 66 which operates at a relatively lower surface speed than the booster Also it is assumed that belt 43, and such bricks are carried up wardly and deposited onto the motor truck 84;.

After the upper layers of the pile of bricks 86 have been moved in the manner above described, the walk 81 is removed, the sliding bars 77 housed within the frame work 10, and the lower layers of brick are loaded onto the conveyer belt. After a number of brick have been removed from one end of the barge 82, the deck of such barge will be tilted in the direction of the heaviest end thereof, and to counteract the tendency of the apparatus to slide in the direction of said inclination, the hinged plates 17 are swung about their pivot to disengage the non-circular portion 18 thereof from engagement with the non-circular portion 15 on the vertical shaft 13, and such shaft 13 is rotated through an angle of whereupon the hinged plate 17 is again swung into position to lock such shaft 13 in adjusted position, the position of the raster wheels 11 on each side of the frame work 10 being now that shown in Fig. 1. Should, for any reason, the load of brick on one side of the barge be heavier than the load on the other, the deck of the barge will have a tilt laterally from the horizontal, and to counteract such tilt, the hand wheels 16 of the appropriate vertical shafts 13 are retated to the right or left to raise or lower the contiguous portion of the frame work 10 with respect thereto, to bring such frame work into substantially a horizontal position.

As the unloading progresses, the apparatus is moved on its caster wheels 11 laterally of itself and longitudinallv of the barge 82 until all the bricks on such barge have been unloaded. Should the tide, during the unloading operation, rise to such an extent that. the delivery end of the upwardly inclined endless conveyer belt 66 be at too great a height above the receiving truck 84, the outer, or free, end of the hingedly mounted frame work 5; is lowered, as above described, tov lower the outer, or free end of the frame work 53 to any height with relation to the truck 84 that may be desired.
